UNITED STATES PATENT OFFICE.

ERNEST JOSZ, OF GANSHOREN, BRUSSELS, BELGIUM, ASSIGNOR TO SOGIETE ANONYME DU JOXYL, OF KOEKELBERG, NEAR BRUSSELS, BELGIUM.

PROCESS OF PRINTING ON WOOD.

To all whom it may concem:

Be it known that I. ERNEST Josz, a subject of the King of Belgium, residing at (iranshoren, Brussels, in the Kingdom of Belgium, have invented new and useful Improvemrnts in Processes of Printing on Wood, of which the following is a specification.

This invention relates to a process for obtaining single color or polychromic impressions on wooden surfaces and veneers in such a manner that any desired ornamental or decorative effects or designs on wooden surfaces are obtained by direct printing with fatty colors or inks, and by the cooperation of the natural structure of the wood.

With this object in view my invention essentially consists in suitably preparing the wooden surface which is to be printed upon so as to remove the difficulties caused by the irregular nature of the wood and then printing directl the prepared surfaces of wood lithographically or by other graphic methods.

In carrying my invention into practice the Wooden surfaces or wooden veneers are rendered homogeneous by applying to them solutions which are capable of re ularly absorbing fatty matter, besides being elastic, waterproof and transparent. This treatment damages neither the color nor the structure of the wood; primings are entirely dispensed with, and it is possible, by the printing on of decorations with lithographic or other fatty colors, to obtain prints which penetrate into the wooden surfaces and which have the desired effect, especially the effect of inlaid work, as well as enamel and other paintin The following mixture is em loyed, for example, for the preparation of the wood:

Turpentine 700 Benzene 650 Linseed oil 20 India rubber solution 50 Oanadabalsam White wax 30 pagts 2y we ght Specification of Letters Patent.

Application filed November 15, 1907.

Serial No. 402,359.

pentine, linseed oil and benzene or with a solution having similar properties. As a further example of a solution of india rubber suitable for the purpose the following compound may be cited:

India rubber (par:1) 100 gr. Turpentine 1000 gr. Copal or other fatty \arnish 500 gr.

lithography, book-printing or by any other mechanical printing method.

Lithography is most suitable of all, if the print to be produced lends itself to chromolithography, and in such a case the printing is best done by a metal printing lithographic press.

If the printing is to be done typographically, it is done by means of a typographic platen or flat printing press.

If more or fewer parts of the printing produced by lithography or typography are required to appear in relief or intaglio, the printis first produced quite fiat by one of the methods above mentioned, after which the desired parts are pressed down by suitably engraved metallic matrices by the aid of an embossing press. In like manner it is also possible to reduce in a single operation raised prints which stand out on a colored ground in the natural color of the wood.

or this purpose all that is required are matrices of the kind mentioned engraved in intaglio and the printing surfaces of which are supplied with the particular color by means of an inki roller; by pressing the ,wooden tablet a alnst the matrix, the surface of the woo is only colored by those portions of the matrix, which are not sunk, while those portions of the wood which enter the sunken parts appear as uncolored raised portions. If on t e other hand the raised parts are to appear colored also, but in a color different from that of the ground, the

sunken parts of the matrix are first inked with the color to be imparted to the raised parts of the wood, the color is removed from the face of the matrix with a blanket roller, and then the other color which is to form the ground is a plied to the face thereof by means of an inking roller. The printed surfaces subsequently receive a coating of varnish or spirit lacquer, for the purpose of pro tecting the print or imparting brilliancy thereto. This coating may be applied with a brush or by a varnishing machine; wax varnish gives a dull coating.

Having thus described my invention, what I claim is:

1. The process of printing on wood and veneers, which consists in applying to the wooden surface a transparent coating adapted to absorb fatty inks, and then mechanically printing ornamental and decorative designs thereon, whereby the natural structure of the wooden surface is adapted to cooperate with the printed design to secure an ornamental effect.

2. The process of printing on wood and veneers; which consists in applying to the wooden surface a transparent coating ada 't ed to absorb fatty inks, then mechanicaldy printing ornamental and decorative designs thereon, whereby the natural structure of the wooden surface is adapted to cooperate with the printed desi n to secure an ornamental effect, and fina 1y applyin a protecting coating upon the printed sur ace.

3. The process of printing on wood and veneers, which consists in applying to the wooden surface a transparent coating adapted to absorb fatty inks, printi on said coated surface with fatty inks, Sub ecting the printed wooden surface to the action of suit ably engraved matrices, and finally applying it protecting coating upon the printed surace.

4. The process of printing on wood and veneers, which consists in applying to the wooden surface a transparent coating capable of absorbing fatty inks, mechanically printing polychromic designs on said wooden surface with fatty inks, whereby the inks are caused to be absorbed by the transparent coating, subjecting the printed wooden surface to the action of suitably engraved matrices, whereby ornamental and decorative effects of inlaid work are produced with the cooperation of the printed polychromic de sign, and finally applying a protecting coating upon the printed surface.

5. The process consisting in applying to a wooden surface a coating of a solution of indie-rubber mixed with a solution of wax and Canada balsam in turpentine, linseed oil and benzene and then printing the said coated surface with fatty inks and finally applying a protecting coating upon the printed wooden surface substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

ERNEST J OSZ.
